Abstract

A capsule delivery system provides for the delivery and dispensing of fluid or semi-fluid admixtures into concrete mixes. The capsule is made of a plastic resin and contains a pre-measured dosage of admixture. Once the capsule containing the admixture enters a concrete mix and the concrete mix is agitated mechanically such as via a concrete ready-mix truck, the plastic resin delivery and dispensing capsule shatters and breaks down unnoticeable to the unaided eye, releasing the encapsulated admixture into the concrete mix.

Claims

AMENDED CLAIMS [Received by the International Bureau on 12 August 2005 (12.08.2005) ; original claims 1 - 16, replaced by amended claims 1 - 12]
1. An device for delivery of a semi-fluid or fluid concrete admixture for a concrete mix to be mechanically agitated, the device comprising: a hollow capsule body is a impact-adjusted crystal polystyrene plastic resin, durable when whole, but suitably brittle so as to shatter and fracture; said hollow capsule body is at least partially filled with the admixture; said hollow capsule body having a plurality of groove like indentations; whereby the mechanical agitation of the concrete mix shatters, fractures and breaks said hollow capsule body releasing the admixture.
2. The device for delivery of a semi-fluid or fluid concrete admixture for a concrete mix to be mechanically agitated as recited in claim 1 wherein said impact- adjusted crystal polystyrene plastic resin is comprised of standard fillers blended into basic polystyrene resin whereby the polystyrene molecule chains separate and weaken.
3. The device for delivery of a semi-fluid or fluid concrete admixture for a concrete mix to be mechanically agitated as recited in claim 1 wherein said hollow capsule body has a thickness of between approximately 1/96 of an inch to approximately lA of an inch.
4. The device for delivery of a semi-fluid or fluid concrete admixture for a concrete mix to be mechanically agitated as recited in claim 1 wherein said hollow capsule body is shattered and fractured by the mechanical agitation of the concrete
20 17
mix into a size unnoticeable to the unaided eye.
5. The device for delivery of a semi-fluid or fluid concrete admixture for a concrete mix to be mechanically agitated as recited in claim 1 wherein said hollow capsule body is egg shaped.
6. A method for delivery and dispensing of a semi-fluid or fluid concrete admixture for a concrete mix to be mechanically agitated, the method comprising the following steps: forming a hollow capsule body of impact-adjusted crystal polystyrene plastic resin, durable when whole, but suitably brittle so as to shatter and fracture; introducing the admixture into said hollow plastic capsule body; sealing said hollow plastic capsule body; introducing said hollow plastic capsule body into the concrete mix; whereby the mechanical agitation of the concrete mix shatters, fractures and breaks said hollow plastic capsule body releasing the admixture.
7. The method for delivery and dispensing of a semi-fluid or fluid concrete admixture for a concrete mix to be mechanically agitated as recited in claim 6 wherein said impact-adjusted crystal polystyrene plastic resin is comprised of standard fillers blended into basic polystyrene resin whereby the polystyrene molecule chains separate and weaken. 18
8. The method for delivery and dispensing of a semi-fluid or fluid concrete admixture for a concrete mix to be mechanically agitated as recited in claim 6 wherein said hollow plastic capsule body is inert to the admixture and the concrete mix.
9. The method for delivery and dispensing of a semi-fluid or fluid concrete admixture for a concrete mix to be mechanically agitated as recited in claim 6 wherein said hollow plastic capsule body has a thickness of between approximately 1/96 of an inch to approximately lA of an inch.
10. The method for delivery and dispensing of a semi-fluid or fluid concrete admixture for a concrete mix to be mechanically agitated as recited in claim 6 wherein said hollow plastic body is shattered and fractured by the mechanical agitation of the concrete mix into a size unnoticeable to the unaided eye.
11. A method for retarding hydration of residual or returned concrete mix for recycling, the method comprising the following steps: providing a hollow capsule body of impact-adjusted crystal polystyrene plastic resin, durable when whole, but suitably brittle so as to shatter and fracture, the body containing a semi-fluid or fluid retarder or delay setting chemical admixture; introducing said hollow plastic capsule body into a ready mix truck; agitating the concrete wherein said hollow plastic capsule body shatters, fractures and breaks to releases said admixture; thereby allowing the concrete mix to be recycled in a subsequent load of concrete mix. 19
12. The method for retarding hydration of residual or returned concrete mix for recycling as recited in claim 11 wherein said impact-adjusted crystal polystyrene plastic resin is comprised of standard fillers blended into basic polystyrene resin whereby the polystyrene molecule chains separate and weaken.
